Thanks for replies Kefalas and Delboy.
At this point I can only go by what I saw at the time I bought this house inJune, the box came with it and previous owner showed me what was possible. The programmes in which he was interested did not include BBC-said you need a different card for that, presume he meant subscription- but he received ITV and sports channels. Generalisations, I know, but then I’m not interested in sport or ITV! If you are seriously interested I can e-mail previous owner.
